Biography
al-Hadi was the eldest son of Caliph al-Mahdi and al-Khayzuran, and he was a Sunni Muslim Bedouin. As caliph after his father's death in 785, he was very open to the people of the empire, and he allowed civilians to address him in his palace in Baghdad. His short rule was wreaked with military conflict, including Husayn ibn Ali ibn Hasan's revolt in Medina in the Battle of Fakhkh of 786, a Khawarij rebellion, and an invasion by the Byzantine Empire. He died in 786, and he was succeeded by his younger brother Harun al-Rashid.
